The Neuroscience of Navigation: Understanding the Brain's Internal Compass.

Scientists have gained new insights into the part of the brain that gives us a sense of direction, by tracking neural activity with the latest advances in brain imaging techniques. The findings shed light on how the brain orients itself in changing environments and even the processes that can go wrong with degenerative diseases like dementia, that leave people feeling lost and confused. The researchers expect that a better understanding of how the brain’s internal compass and navigation system works will lead to earlier detection and better assessment of treatments for Alzheimer’s disease.
